When I studied the Qadr of Allah i wondered if the acceptance of His Qadr is interrelated to the acceptance of laa illaha illa llah? Or if one by the Will of Allah perfected acceptance of His Qadr, is it going to have positive impact on accepting the kalimah and vice versa? Jazakumullahu khair.
Yes, definitely there is a very strong and direct relation. Believing and accepting Allah’s qadar is from the requirements of la ilaha illa Allah. And this is a great act of worship. Each and every act of worship increases your faith in your heart. And the more the faith is in your heart, the more is your acceptance of Qadar of Allah.
